Waiting for my King PDM-30 mill to arrive and wonder what is the best collet system for round column mills. I have no experience with mills and only recently discovered there are different collet systems for the R8 taper in this mill drill. From info supplied on another thread, I understand one of the issues of the round column mill is that the X Y register is lost whenever the head is moved vertically. So I wonder if it is better to use an ER system than a drawbar collet. I envision the drawbar collet system requiring more vertical clearance to make changes from one size end mill to the next, since the whole collet has to be removed and they are much longer than ER collets. Can drill bits be used in ER collets?
